Characterization of Near-Nadir Ka-Band Scattering from Wet Surfaces
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Preliminary assessments of near-nadir Ka-band data from the airborne SWOT (AirSWOT) platform revealed complexity in the classification of water surfaces due to heterogeneous surface phenomenology. A survey of radar scattering literature for water surfaces indicated a dearth of knowledge surrounding Ka-band scattering for heterogeneous regions ...

Peakedness Effects in Near-Nadir Radar Observations of the Sea Surface
IEEE Transactions on Geoscience and Remote Sensing, 2012The simulation and interpretation of microwave sea radar return in the near-nadir region are still issues in view of the limitations of the geometrical optics approximation and the multiscale and non-Gaussian nature of the surface. We show that an unambiguous and fully consistent physical approach can be reached in the framework of the physical optics.

KaRIn on SWOT: modeling and simulation of near-nadir Ka-band interferometric SAR images
Proceedings of SPIE, 2010The principal instrument of the wide-swath altimetry mission SWOT is KaRIn, a Ka-band interferometric SAR system operating on near-nadir swaths on both sides of the satellite track. Due to the short wavelength and particular observation geometry, there are very limited reports on the backscattering from natural surfaces.

Analysis of Lava Tubes’ Roughness and Radar Near-Nadir Regime Backscattering Properties
IEEE Transactions on Geoscience and Remote Sensing, 2023Lava tubes are terrestrial tunnel-like natural subsurface caves. Mounting evidence suggests their presence on the Moon and Mars. Planetary radar sounders are nadir-looking instruments operating in the high-frequency (HF)/very-HF (VHF) part of the spectrum with subsurface penetration capabilities. Recently, several studies either proposed future mission
